Use this card on "Elemental HERO Absolute Zero" to activate its effect to clear the opponents field. Then attack with the material monsters for decent damage.

"Elemental HERO" Decks really beneficent from this card in general since there are a few "HEROes" whose effects only activate upon Summoning and "Neos Knight" can net you either two "Neos" or a "Neos" and "Bladedge" both whom are powerful monsters in ATK power who can cause battle damage.

"Gem-Knight" Decks can benefit the same way. In addition, they can also use "Pyroxene Fusion" to re-fuse the monsters, allowing for substantial swarming during the Battle Phase.
